If you’re flying outside the US, the rules are pretty universal. The EU, UK, Australia, and Canada all follow similar guidelines—electric toothbrushes in carry-on are a-okay. However, some countries like Japan or South Korea have stricter battery size limits, so check their civil aviation website. But seriously, when was the last time you saw a toothbrush with a battery bigger than a candy bar?
One exception: if your brush uses a NiMH (nickel-metal hydride) battery, you’re even safer—those are rarely restricted. Just be aware that older models might not hold a charge as well. I once had a brush die mid-flight, and I had to pretend I was a caveperson for the rest of my trip.
Final Thoughts—and a Little Irony
So, can you take an electric toothbrush in hand luggage? Yes, without a doubt. But the ironic part is: while you’re obsessing over your toothbrush, you’ll sail through security, and then you’ll have to worry about something else—like why that guy behind you brought a full-sized jar of peanut butter. Priorities, people.
Bottom line: keep it charged, lock the button, and don’t overthink it. Your electric toothbrush is more welcome in the cabin than your half-empty water bottle. Happy brushing, and safe travels! Just don’t forget to brush your tongue at 30,000 feet—it’s oddly satisfying.
